Blade fatigue, due to cavitation in rocket engine turbopumps, often triggers catastrophic system failures, costing insurers of space missions, launch vehicle operators and their customers billions of dollars every year. Next Planet Research’s Supercor VFI-689 / Vortex Force Impeller (VFI) System can potentially reduce rocket engine failures by optimizing launch vehicle performance and improving aerospace industry safety margins.
The combined effects of hydrodynamic cavitation and unbalanced rotordynamic forces, as well as the accumulation of turbopump operational efficiency losses can trigger a cascade of rocket motor propellant fuel feed subsystem and component malfunctions that can result in catastrophic failure. ...

This invention relates to the field of Tactical Shooting skills development and measurement. Specifically, the invention consists of a device that laser-points targets in a random sequence. The targets will automatically change each time the device detects a new shot, thus generating an arbitrary series of marks for its user to shoot.
Presently, there are many known methods for target shooting training to develop and improve rapid target acquisition and random target acquisition skills. When using real ammunition, they are:
• Mechanical moving targets
• Shooting of living creatures
• Unique symbol targets (each target has a unique ...

The Tesla Turbopulsejet is a (hypothetically) low cost, highly efficient and compact jet engine, using patents and inventions from 20th century inventor Nikola Tesla, as well as the use of pulse jet engines. The pulse jet aspect improves combustion efficiency by doing combustion in pulses, reducing fuel consumption over time.
A typical jet engine exhaust turbine can't handle pulses all that easily, so the exhaust scroll of choice is the Tesla turbine, a centrifugal turbine consisting of a series of perforated discs mounted on a drive shaft, powered by tangentially shooting air in between the discs. Estimates are that Tesla ...
Hybrid Remotely-operated underwater vehicle (H-ROV) is a robot that completes functions underwater on behalf of a crew, located on the surface, with whom the H-ROV is tethered. These functions include: search/recover, inspection, equipment repair, scientific analysis, dredging/trenching, cable-laying, and surveying.
H-ROV is designed to work at desirable depth. It is steered by turning a rudder left and right and it adjust the altitude under the water by tilting the elevators. Water- pushing and creating a forward force is done by a propeller. A power source is engaged on this action with transmitter and receiver of 6 channel. It has ...
Airfoil wings make lift by changing the direction and pressure of the air that crashes into them as they move through the sky. The spinning cylinder wing design, using the magnus effect and has many advantages over traditional airfoils but also some disadvantages. This design is a type of merger of these two known technologies in such a way as to make use of the advantages of both while eliminating the disadvantages. Some of the advantages are: More wing lift and less drag!
Instead of the solid, rigid, stationary design of a traditional airfoil, the Magfoil has an outer ...

The Torso in a Box replicates the anatomical variation in material properties of the intended target. Panels of material simulating skin, muscle, bone and the internal organs are layered in the appropriate order to create a model for testing the effectiveness of self defense ammunition on the intended target. All of the materials in the Torso in a Box are recyclable so once you perform your test and determine the wound cavity, you can drop the box in the recycle bin.
Unlike ballistics gel, the Torso in a Box is easy to use. Just set it down range and ...
Here I have attached my design which speaks about how the drone can transform itself into a hybrid vehicle. The theme is wheel portion rotates on the elliptical base with respect to elliptic's center axis in order to transform itself to a drone. When it is in drone form, power transmits from motor to blades; when it is in vehicle form power transmits from motor to wheel. That's all simple ...
The project is to design a gas turbine from type turbofan engine and the provision of jet fuel in the use of clean energy and renewable energy is hydrogen.
Known that we are consuming large amounts of fuel on flights around the world, hence the idea of using hydrogen combustion inside the engine, where they are providing fuel ratio between 10-27% of the fuel consumption and the extraction of hydrogen from water in the cell electrolytic decomposition, which in turn found in the aircraft wing or at the bottom of the plane.
And the withdrawal of gas resulting from ...
Reaction wheels (RWs) are not only the standard solution for attitude control of conventional spacecraft such as telecommunication satellites, but they are also frequently used in smaller satellites with demanding attitude control requirements. Due to their simplicity and compactness, ball bearings are commonly utilized for mounting RWs, especially in smaller satellites. However, ball bearings have several disadvantages. For instance, mechanical friction and wear limit the reliability and lifetime. Moreover, RWs with ball bearings are usually operated in a hermetically sealed atmosphere for preventing the outgassing of the bearing lubricant, which adds to the weight, cost and the complexity of ...

This design is based in more than five years of experimentation, which was originated by our aim to make the High UVI/RH coastal Peruvian desert.
Mars UVC & UVB at surface is assumed to be ~ 10 times Earth and UVA close to our planet values. This is a tremendous energy that can be used for a photochemical job. UVC & UVB flux in Mars is ~ 400 W/M2/day while in Earth is on average 40. For that energy, we use a brine soluble catalyst/susceptor made naturally from the Aloe plant (Aloin) Our discovery is that by decomposing the ...
